HAND-THREADING LOOM SHUTTLE.

Y, Specification of Letters Patent.

jatented Apr. 18, 192.2.

Application led January 4, 1921. Serial No. 434,888.

To all whom t may comer/ri:

Be it known that I, JEAN B. IDAUDELIN, a citizen-of the United States. residing at Fall River7 county of Bristol, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Hand- Threading Loom Shuttlea'of which the following is a specification.

This invention relates to hand threading loom shuttles and particularly to the eye piece for the threading eye. My invention involves certain improvements over the eye piece shown in my prior Patent No. 1,248,- 627, December f1, 1917. to which reference is made as illustrating the. particular type involved herein. LThe present invention contemplates certain improvements whereby the eye piece is more securely fixed in the threading eye and also involves certain refinemente in the construction of the eye piece itself, all as will appear more fully hereinafter. f

The construction and operation of .'my device, together with a selected embodiment which well illustrates lthe principles of my invention, is described in the followingV specification vand particularly shown in the drawingsforming a part thereof. Throughout the specification and drawinds like reference characters are employed to indicate corin the drawings Fig. I is apartialplan view of the threading end of a shuttle equipped with my -invention. 5

Fig. II is a side 'elevation thereof as viewed from the right in Fig. I.

. FigIII 'is' a similar elevation'as viewed from the leftin Fig." I

Fig. IV is a transverse section on the *line IIT-IV, Fig. I.

Figs. V and VI are perspective views of the eye piece removed and viewed from op- A* Fig. VII is a at the shuttle throat,v removed.

Y I have indicated atl the body lof a hand ed .a bobbin 3 carrying the filling F. The throat of the shuttle opensinto' an eye 4 which extends across the shuttle as a transverse-.bore of'substantially cylindrical form,l

and is counterbored as clearly shown in Fig. III. Leading `from the shuttle throat is 'they-eyepiece within the eye.V Y piece as here shown 1s formedfas a substanv18 has an upwardly which extendsforwardly alongthe upper' face` of the shuttle, 'as appears 1n Fig. I, to the side wall thereof and thence downwardly and back- ".va'rdly along said side wall to connect with. the outer end of the threading eye, as appears in Fig. III.

As here shown,

and arranged to permit the shuttle to be rapidly the eye, is nonetheless securely fixed therein.

`According to my invention the eye piece need not be shaped tov snugly giit the eye but instead mayloosely it therein, mechanical means being provldedto positivelyiit Such eye tially cylindrical lowerl section f 7 and a rounded upper section 8. conforming roughly to the shape-vof theveye itself.- The section 7 at the farv side of the shuttle (see Fig. III) is longitudinally grooved as indicated at 9. Fig. V, to receive a horizontally disposed securingv pin 99 and on its opposite side is vertically grooved as indicated at 10, Fig. VI. to lcceive a vertical securing-pin 100. The pins 99 and 100 thus fix-the eye piece against both longitudinal and lateral movement in the eye.

Between its ends and substantially in line withthe axis of the bobbin the eye piece 1s vertically slotted as indicated at 1.1 providing a port through which'the vfilling from In threading, the lling n Y under acurved guard pin`17 to the port 11 and thence into the threading slot 12 of the shuttle which lays it into the eye piece from abovev the outer 'lor delivery end thereof. The eye piece at its delivery end is cleared away at one sideof its longitudinal axis, as indicated at 18, 'VL and opposite said cleared portion curved lip portion113 whichextends above the plane of entry-of the eye piece' 6 is a solid- `member.preferably of porcelain, constructed Y and easily threaded and when threaded tofeffectively guide the filling rdi- -fet the slot l2 into the eye and directs the filling into the eye piece. From said portion the `filling descends into a port lelcommunicating with the port ll and spaced therefrom by a guide and snubbing post i5. The shuttle is now threaded. After threading, the filling runs directly from the bobbin through the port ll around the base of the snubbing the pathv of travel of the filling.

throat in' advance of the inlet port l1, and may be a simple pin having a pointed yentering end and a bent guarding end which may be carried down into the wood oil the shuttle so as to form an overlying curved bar under which the filling runs 'from the bobbin.

Various modifications in the form and construction oi my device may obviously .be resorted to all without departing` from the spirit of the invention if within the limits of the appended claims. v

What I therefore claim and desire to secure by Letters Patent is 1. An eye piece for a shuttle eye, consisting of a member having a thread passage terminating inr spaced ports and having a guiding portion between said ports and overhanging the passage connecting said ports, said eye piece beyond. said guiding portion cleared away at one side of its longitudinal axis, and a lip on said eye piece at the opposite side of its longitudinal axis and overhanging said cleared away portion and effective to lay the filling *intov the eye piece' from Yabove in threading and to prevent escapc of the filling by a direct upward movement after threading.

2. In a shuttle having a threading eye, an eye piece loosely fitting said. eye and having angularly disposed grooves, securing pins disposed in said grooves and fixing the 'eye Vpiece against longitudinal Vand lateral movement in said eye, said eye piece having its delivery end cleared away at one side of its longitudinal axis and opposite said Ycleared portion having an upwardly vdis- -posed lip effective to lay the filling into the; veye piece from above in threading 'and to l prevent escape of the `filling l ward movement after threading. f l

5.

and said groove extending past the base of said guiding element, and connecting the threading port with thedeliveryT end of the eye piece.

and said groove extending past the base of said guiding element, and connecting the threading port'with the delivery end of the eye piece, and said lower portion of the eye piece adjacent the delivery end of the eye being cleared. away, and a guard lip on said lower portion of the eye piece overhanging said cleared away portion.

In testimony whereof I aliix my signature in presence of two witnesses.
